孕妈们对叶酸都不会陌生，医生会建议从孕前3月始每天适量补充叶酸，以预防胎儿神经管缺陷。然而，近日话题“叶酸吃多了真的会致癌吗”一度登上热搜榜第一，引起了网友的广泛热议。记者采访江苏省第二中医院妇科副主任王旺主任医师得知，长期大剂量补充叶酸（大于1mg/d）有可能存在安全风险。
王旺主任医师表示，叶酸是孕期非常重要的营养素，合理的补充对母婴健康有益。但过量补充叶酸可能导致染色体异常，从而增加患癌的风险。研究发现，长期大剂量补充叶酸的孕妇，胎儿出现神经管缺陷的风险降低，但同时患癌风险增加。
王旺主任医师提醒，孕妇在补充叶酸时应遵循医生建议，适量补充，切勿盲目自行增加剂量。此外，孕期应保持良好的生活习惯，均衡饮食，加强免疫力，定期进行产检，以确保母婴安全。

Maternal nutrition plays a crucial role during pregnancy, and folic acid is no stranger to expectant mothers. Doctors generally recommend that women supplement with an appropriate amount of folic acid starting from three months before pregnancy to prevent neural tube defects in the fetus. However, recent discussions about the potential cancer risk of excessive folic acid intake have sparked widespread debate among netizens. Journalists interviewed Wang Wang, deputy director of the Gynecology Department at Jiangsu Province Second Traditional Chinese Medicine Hospital, who explained that long-term high-dose folic acid supplementation (>1mg/d) may pose safety risks.
According to Wang, folic acid is an essential nutrient during pregnancy, and appropriate supplementation is beneficial to maternal and fetal health. However, excessive supplementation of folic acid may lead to chromosomal abnormalities, thereby increasing the risk of cancer. Research shows that while the risk of neural tube defects in infants decreases with long-term high-dose folic acid supplementation, the risk of cancer increases among mothers.
Wang advises expectant mothers to follow their doctors’ recommendations when supplementing with folic acid, avoid blindly increasing doses, and maintain good habits, balanced diets, enhanced immunity, and regular prenatal checkups to ensure the safety of both mother and baby.
